php use 32 bit dll for execution, x64 IIS server not able to run php in
x64 web server. But there is a way to run php in x64 windows server.
First, you need to emulate your server in 32bit mode. To do this,
1. Goto Start
2. Then Click Run
3. And type “cmd” without cottesion. Then Press Enter Key.
4. Type “C: ” and then press enter.
5. Type “CD\ ” and enter.
6. Type “CD Inetpub\Adminscript” and press enter.
7. Type “adsutil.vbs set w3svc/AppPools/Enable32bitAppOnWin64 0″ and enter. this will enable your x64 server x86 emulating option.
8. Then normally install php and run it.
To Disable emulation you need to type this command on that folder.
adsutil.vbs set w3svc/AppPools/Enable32bitAppOnWin64 1
Thanks. I think you can do this.
And for registering 32 bit dll files,
use
C:\Windows\SySWoW64\REGSVR32not only,
REGSVR32i think it work for you x64 guy also. it worked for me.
